TAKE-UP MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 695,373, dated March 11, 1902.

Application filed September 21, 1901. s i l No. 76,057. (No model.)

To a whom it may concern.-

Be it known that I, .ZEBULON L. CHAD- BOURNE, a citizen of the United States, residing at New Brighton, in the county of Richmond and State of New York, have invented new and useful Improvements in Take-Up Mechanisms for Looms, of which the following is a specification.

My invention relates to a take-up mechan ism for looms. This mechanism is particu larly designed to be used on a hammock-loom covered by application for patent, Serial No. 59,118.

The object of my invention is to construct an intermittent take-up which, in combination with a drum driven by a friction-motor, will keep the fabric taut. The novel construction by which this object is attained is fully described in this specification and illustrated in the accompanying drawings, forminga part thereof, in which- Figure 1 is a plan view of the rear portion of my loom with my device attached thereto. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical longitudinal section of the same. Fig. 4 is a detail of the gearing. Fig. 5 is a detail of the four-armed cam. Fig. (i is a detail of one of the pins and spring, together with fragments of the disks.

Like numerals of reference designate like parts in the different views of the drawings.

The numeral 1 designates the rear frames of the machine, and 2 a pin-bearing sag-roller on which the fabric rests after passing from the weaving mechanism of the machine. Located justback of the sag-roller2 are two feedrollers 3 and 4-2. lower large one and an uppersmallerone,respectively. Thelower roller 3 is supported on spindles 5 and 6 and the up- ..per roller 4 is supported 011 spindles 7 and S.

The spindle 5 has keyed thereon a gear 9,which meshes with a smaller gear 10, keyed on the spindle 7. The ratio of the diameters of the gears 9 and 10 is equal to the ratio of the diameters of the rollers 3 and 4. The spindles 7 and S are mounted in boxes 11 and can be vertically adjusted by means of set-screws 12, carrying sliding blocks 13, within which the spindles fit.

In order to drive the feed-rolls 3 and 4, a gear 14 is keyed on the spindle 6, which gear meshes with a gear 15, mounted to turn on a stub-shaft 16 and having a hub bearing a ratchet 17. A pair of pawls 18 mesh with the-ratchet 17 and are carried by a lever 19, fulcrumed on the shaft 16. The outer end of the lever 19 is slotted at 19, and the upper end of a connecting-rod 20 is pivoted thereto on a bolt 20, adjustably mounted in said slot. By this arrangement the throw of the lever 19 can be regulated. A ratchet 21 is keyed on the outer end of the spindle 5 and is engaged by a pawl 21, mounted on the frame. This combination of pawl and ratchet prevents slacking off of the feed when the pawls 18 are taking a new hold.

The lower end of the connecting-rod 20 is pivoted to the long arm 22 of a bell-crank lever 22, Whose short arm 22 bears a roller 23, which is positioned to be engaged by the arms 24 of a four-armed cam 24, keyed on a main shaft 25. The shaft 25 has a beveled gear 26 keyed thereon, which beveled gear meshes with a second beveled gear 27 keyed on a shaft 28, which is driven by some source of power.

The gearing is so proportioned that at each movement of the weaving mechanism one of the arms 24 will engage the roller 23 and actuate the connecting-rod 20 to operate thelever 19 to turn the rollers 3 and 4 to feed the fabric which passes between them.

The fabric passes from the rollers 3 4 to a drum 29, which is located in the extreme rear of the machine and is supported on spindles 30, journaled in, open boxes in the frame of the machine. For driving the drum 29 a friction-motor is provided. This motor comprises a disk 31, slidingly mounted on the right spindle 30, adjacent and parallel to a disk 32,keyed on said spindle. The disk 32 has a threaded aperture in each quadrant, Within which are mounted pins 34,surrounded by coiled springs 35 and having enlarged grooved heads 36, provided with threads and screwed into the apertures 33. The pins 34 fit loosely apertures 37 in the disk 31, and the springs 35 bear at their outer ends on this disk. turning the heads 36. By the pressure of the springs 35 the inner face of the disk 31 is held in contact with a large friction-disk 38, mounted on a stub-shaft and driven by a pulley 39, connected thereto by a hub 39. The

This pressure can be regulated by pulley 39 is driven by means of a belt connecting it to a pulley 41, keyed on the main shaft 25. driven by a friction-motor the pull on the fabric is maintained constant and does not vary with the amount of fabric on the drum. It should be noted that the right spindle 30 is made in sections secured together by a cross-pin 42. This enables the drum to be replaced when full by an empty one;

Having described my invention, what I claim as new, and wish to secure by Letters scribed.

2. In a'take-up mechanism, the combina- By this arrangement of a drum tion with'a drum constructed to wind fabric on and bearing a spindle, of a friction-disk slidingly mounted on said spindle, of a disk mounted on said spindle parallel to said friction-disk, springs mounted on said disk and bearin g on said unyielding friction-disk, and a second friction-disk mounted to contact with and actuate said friction-disk on said spindle, substantially as described.

3. In a take-up mechanism, the combination with adrum provided with a spindle, of a friction-disk loosely mounted on said spindle and having apertures therein, of a disk rigidly mounted on said spindle parallel to said friction-disk,pins adj ustably mounted in apertures in said fixed disk and engaging said apertures in said friction-disk, springs surrounding said pins and bearing on said friction-disk,and a second friction-disk mounted in contact with said first-named friction-disk, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
